Air pressure adjusting module having variable blade device of independent structure

Abstract

An air pressure adjusting module having variable blade device of independent structure is disclosed. The device being connected to an oil supplying device mounted with a nozzle having an external throttle and an internal throttle provides a finer and homogeneous atomized air-oil mixture which enhance the lubricating effect.

I claim: 
     
       1. An oil atomizing device to lubricate pressurized air in a compressed air system, the device comprising: an oil supply cup; a nozzle; an oil guiding tube connected between said nozzle and said cup to direct oil from said cup to said nozzle; a chamber having an air inlet extending from the chamber to the exterior of the device, the air inlet having a circular shape; a conical flow guide mounted in the chamber having a flow guide air inlet of circular configuration and a flow guide air outlet of square configuration; a plurality of resilient flaps located at the air flow guide outlet; a lateral wall of the flow guide and chamber having aligned holes communicating with the cup, such that the conical shaped flow guide causes a portion of compressed air in the flow guide to flow into the cup containing oil when compressed air passes through the nozzle, such that the lubrication air can be smoothly sucked out. 
     
     
       2. The oil atomizing device of claim 1, wherein the nozzle has an external throttle and an internal throttle. 
     
     
       3. The oil atomizing device of claim 2, wherein the inner throttle has a conically shaped hole.
